WARP-DRESSING MACHINE.

To @ZZ whom it may concern.-

Be it known that I, SieiiUNn (mENHEIMnR, a citizen of the United States, residing at N ew Orleans, in the parish of Orleans and State of Louisiana, have invented new and useful Improvements in lVarp-Dressing Machines, of which the following is a speciticaiion.

My present invention relates to that class of mechanism known in cotton-mills as hotair slashers, or machines for sizing and drying warp-yarns.

Heretofore and prior to my invention the warpyarns have been taken from the beams, carried through the sizing-trough, and thence led into the hot-air chamber or drying-compartment, traversing the latter repeatedly from end to end, until, passing over the last guiding-roll, they emerge at or near the bottom and are carried to the loom-beam, on which they are wound. The capacity of the ordinary hot-air slasher is calculated for a certain quality (as to number of yarns) and quantity, to yards,) and in case where a larger production is necessary or a coarser number of yarns or greater number of threads are used than originally intended and calculated a second slasher must be procured. In some instances, however, attempts have been made to extend the hot-air chamber by adding a second compartment or section,\\'lieieby the size of the said chamber was doubled. The objection to this expedient is that it not only necessitates the removal oi' either the sizing or the beaming mechanism, but it also requires a very considerable extension of the iioor-space,which is in all cases a very serious consideration. Moreover, the cost ot a drying-chamber considerable, and the eXtension of the hot-air compartment involves the duplication of a costly part ot the entire apparatus.

It is the purpose of myinvention to provide a simple an doom parati vely in expensive means whereby the capacity ot' the hot-air slasher may be increased to double its drying capacity, or even more, without occupying addiH tional floorfspace, and without necessitating the purchase ot further heating and drying apparatus and without any additional steam.

The invention consists in the several novel features of construction and new combina tions ot' parts, hereinafter fully set forth, and then specilieally pointed out in the claims.

In the accompanying drawing, the iigure is f1-diagram illustrating my invention.

In the said drawing, the rct'erence-numeral l denotes the warp-beam containing` the warpyarns, and from which they are carried to the sizing-trough 2. From this trough, after passing through the hot-air chamber, the yarns are led to the warp-beam 23. upon which they are wound.

In the ordinary hot-air slasher used prior to my invention the drying-chamber consisted of a compartment, i, having steam-pipes or similar heating mechanism. arranged inside. Into this chamber the yarns were led, passing over a roll on the end, and then traversing back and forth in said chamber over interior alternating rolls, o', until said yarns tinally passed outI at the bottom and at the end opposite that at which they entered and were carried over a roll, 7, then over a second roll, 8, and wound upon the warp-beam 8.

The mechanism thus tar described heilig substantially the same as that already in use, I remove the' top of the hot-air compartment -t and erect upon the latter an extension, et, of substantially equal dimensions, and forming in connection with the compartment 1t a drying-chamber or hot-air compartment having double the capacity of the chamber 4, the entire interior space being heated by the steampipes 5, forming part ot' the hot-air Slasher.

Upon one end of the extension a, at or near the top, is an exterior guide-roll, 9, over which the yarns pass as they come from the sizing trough, and from this roll they pass by an aperture, l0, into the extension t and traverse the same, issuing at the opposite end through a small opening or series of openings, l2, and passing over a second guide-roll, 13. Frein this roll the yarns again pass into the extension, traverse its interior, and emerge through a second opening or openings, it, and pass over a roll, l5, on the exterior of the extension. In like manner the threads or yarns are led back and forth over the series of rolls on the exterior of the extension l until they finally enter the original compartment or chamber 1i. Here they pass from one to the other of the interior rolls, 6, until they reach IOO of air escaping from these openings secures i' the gradual change of air required in the interior, whereby a large body of heated dry or nearly dry air is always present.

It will be seen that by my invention I can greatly increase the capacity of the Slasher without occupying additional floor-space or purchasing new or additional machinery, and without in any manner modifying or changing the construction of the slashers already l in use. The whole interior of the dryingchamber is heated by the steam-pipes 5, forming part of the ordinary Slasher, and any person familiar with the use of tools and having' suitable material can easily practice my invention at Very small expense.

i i i ii i l. In a warp-dressing mechanism or slasher, a hot-air or drying compartment consisting of the ordinary drying-chamber havin g steampipes and yarn-guiding rolls, and provided with a vertical extension havin g exterior guiding-rolls upon its ends and apertures for admitting the passage of the yarns to and from said rolls, substantially as described.

2. In a hot-air slasher or warp-dressing mechanism, the combination, with the sizingrolls, o' a hot-air chamber or drying-compartment consistin'of a lower part having steampipes and interior guiding-rolls and an upper portion or extension communicating therewith, and provided with exterior rolls and with apertures permitting the passage of the yarns through the interior and to and from said rolls of the lower portion, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
